TW200804012A - Method and device for sealing end of metal pipe by rolling and pressurizing - Google Patents

Abstract

The present invention provides a method and a device for sealing an end of a metal pipe by rolling and pressurizing, wherein a pipe of which an end is to be sealed is fit in a spindle-holder for positioning and is secured by using a chuck assembly and a hydraulic assembly. Thereafter, a bi-directional moving assembly moves roller base to have a conic surface of a conic roller carried thereby performing first-stage rolling/pressurizing on the end of the pipe. The end of the pipe is deformed into a cone due to the pressurization. Then, the bi-directional moving assembly moves the roller base again to have a concave curved surface of a concave curved roller carried thereby performing second-stage rolling /pressurizing on the end of the pipe, making the end of the pipe pressurized into a curved configuration. With such a process, manufacturing costs are lowered and the aesthetics of products is enhanced.
